The Research And Application Of Drainage Gas Recovery By The Technology Of Cyclone-atomizing In Yulin Gas North Field

With the continuous development and utilization of gas reservoir, gas well formationpressure and production decline gradually, low-yield wells gradually increased, with varyingdegrees of water production will be well production process (condensate water and formationwater). If not timely bottom of produced water discharge mouth, will be at the bottom of theaccumulation, increase the bottom hole pressure, gas production is reduced, serious when cancause the gas well water flooded; effusion long time in bottom deposits will cause greatpollution and damage to the formation, seriously affected the normal development andproduction of gas field. Therefore, choose the reasonable matching of drainage gas recoverytechnology is the key to ensure normal production measures of gas field. In recent years, withthe increasing of gas wells, gas wells production conditions are becoming more and morecomplex, depending on the gas well production conditions for the gas well production andproduction equipment, into normal production of gas well, extend the production cycle, animportant guarantee to realize the high efficiency gas production. If the method of equipmentselection, because of wellbore fluid discharge is not timely, causing downhole long timeaccumulation effect caused by production wells early production, bring great economic loss.How to solve the problem of gas effusion, choosing a reasonable mode of production, thereasonable equipped with instruments of production, while reducing the ground supportequipment, to achieve energy saving and environmental protection purposes, further improvethe gas production rate, reduce the cost of production has become the important subject facingthe future field development system. In order to improve the drainage gas recovery effect, thefoundation of theoretical research in the technology of gas recovery of swirl atomizingunderground drainage, proposed to improve the liquid gas well fluid carrying capacity, preventwellbore, increase gas recovery, enhance the gas-well capacity and stable yield ability ofapplication swirl atomizing underground drainage gas recovery technology.
